Land line call,didn't know area code,didn't answer.
People who blame DNC are idiots, legit TM's & surveys don't call. "Charities & Political calls are exempt. Real charities will leave messages or are charities that you have given to. Politcal calls usually will just go ahead and leave their message. "Surveys" - you are a real fool to give out personal information over the phone. Unless you know who the surveyor is or have had dealings with them. If you still wish to deal with them,tell them you are busy and will call them back.Then call your information number check that number against the one on caller I.D.-I'm betting you'll be surprised.
REAL SIMPLE- NO name and/or message-DON'T ANSWER
DON'T CALL BACK- IF YOU DO your just confirming that your number is a good one.
If you did call back and tell them not to call or punch a button -again your number is good
Good numbers go on lists,which are used or sold to others to scam or plish you.
